Amrinone is also known as indanone and is a pyridine phosphodiesterase 3 inhibitor when inoculated. This is a drug that can improve the prognosis of patients with congestive heart failure. Amrinone has been shown to increase heart-induced contraction through high calcium-induced calcium release (CICR). The positive inotropic effect of amrinone is mediated by the selective enhancement of high-gain CICR. The highly selective CICR contributes to the contraction of cardiomyocytes through the phosphorylation of cAMP-dependent protein kinase A (PKA) and Ca. 2+ Calcium Regulatory protein kinase pathway.

position. Many flower color substances, called anthocyanins, are tetrahydro-2H-pyranderivatives of tetrahydro-2H-pyranbenzopyran salts, and their basic structure is similar to flavonoids. For example, the pelargonium pigment obtained from geranium flowers, the hydroxyl groups on the benzene ring form glycosides with sugars in the plant body, and the free tetrahydro-2H-pyranhydroxyl compounds are obtained by hydrolysis, which are called “anthocyanins”. The color of this type of substance changes with pH and presents various colors. The hydrochloride is red, the metal salt of high pH is blue, and the neutral compound is purple.
